Application filed December 20, 1911. Serial No. 666,935.

To all whom it may concern Be it known that I, CHAnLns J Coons, a citizen of Great Britain, residing at Albany, in the county of Albany and State of New York, have invented new and useful Imter whereby the capacity of the vehicle may be properly tested as to its efliciency for hill climbing, for braking or drown grades, and other essential tests which have been heretofore carried out on the road.

A further object of the invention is to provide a testing machine which includes an endless belt or movable track which may be shifted so that its inclination may be made to assimulate inclines or down grades and is of such width as to permit the car being properly steered from side to side so that the power and braking capacity of the car may be tested and also its steering A still further object of the invention is to provide a testing device of this charactor-whereby the power developed for driving the vehicle may be utilized in a useful manner, as by operating a dynamo pump or the like to charge storage batteries or to fill an air tank,

A still further object of the invention is the provision of suitable means for steering the vehicle while on the testing machine without making it necessary for the operator to be upon the vehicle so that all liability of danger is thus eliminated.

Further objects of the invention will appear as the following specific description is read in connection with the accompanyin r drawings, which form a part of this application. and in which Figure l is a side elevation. Fig. 2 is a top plan view. Fig. 3 is an end eleva tion. Fig. f is a section on the line 4E4 of Fig. 1.

in the specific embodiment of the inven-v tion as illustrated herein, 1 represents a pitor depression formed in the floor or other surface and having an inclined bottom 9 for a purpose to he hereinafter described. Adjacent one end of tlr bottom 2, there are mounted upon a level portion 3 thereof suitable bearing standards 4 which have mounted in bearings 5 in their upper ends a transverse shaft 6 upon which one end of a suitable frame 7 is loosely mounted. This frame comprises skeleton side members 8 which are connected together by the bridge pieces 9Q Each side member is substantially oval in outline and carries an oval track 10 thereon over which adapted to travel a plurality of Wheels 11 connected together through the pintles 12 upon which they are journaled, of the platform sections 13. These platform sections are hinged to ether by the pintles 12, as shown, and are supported by the wheels upon the tracks so as to constitute an endless belt upon which the automobile or other motor vehicle is adapted to rest during the testing operation.

The sides 8 of the frame have secured thereon adjacent the free end thereof suitable plates 14 from which project stub shafts 15 having loosely journaled thereon bearing members 16. The lower ends of the hearing members are connected to screws 17 which have threaded thereon sleeves l8 journaled in bracket bearings 19. The lower ends of these sleeves carry beveled gears 20 which mesh with similar gears 21 upon a transverse shaft which is operated-in any suitable manner to rotate the beveled gears 20 and thus raise or lower the screws in the sleeves which holds the sleeves l8 is preferably pivoted to the bracket proper so as to permit the screw to assume different angles governed by the position of the free end of the frame in its movements up and down.

In order to balance the weight of the same upon the screws, a cable 23 is connected to the bearing 16 and passes over a pulley 2d and has its free end suitably weighted as shown at 23, the weights being preferably ren'lovable so as to make the balance device adj ustablc.

Extending upwardly from the side plates 8 are standards 26 in the upper ends of which are secured rearwardly extending support ing members 27 having bearings 28 at their rear ends. Reinovably mounted in these hearings is a. bar :29 which is held in rigid posit-ion therein by screws 30. This bar has slidablv mounted thereon a ring member 3'1 to which a cable is attached, the oppo-v site end of the cable being connected to any The bearing portion of the bracket motor vehicle so that when in. operation, the

same will be prevented from traveling forward over the frame. When the bar 29 is not i we, a. bollai-tl secured to the floor pic "ably used. When the machine is cumw'tetl t0 the sliduble ring 31 tllruugli the czt'nlz "2 and steered tram right to left on flit: moving platform, the ring will slidc .ipon the rod 29 so that a straight cable will line and bar and no ill'illtl strain will he placed upon, the vehide.
